Voip One Click is an Android app which allows users to make free encrypted VoIP calls. It uses the TLS protocol to encrypt the information call (caller id /called id), and the SRTP protocol to encrypt the audio communication.

Voip One Click enables users to dial and receive mobile voice calls which cannot be intercepted.

The app works with WiFi/3G/satellite connections everywhere there is internet access. It guarantees high voice quality without delay even when used on mobile networks 3G/UMTS.

The application can be used directly after installation, without any configuration or registration required.

In order to make encrypted calls both parties should use Voip One Click but you can call with improved privacy even the normal phone numbers. It also works when VoIP is banned by the local internet provider, if used together with the VPN service Vpn One Click.
